Hi,

I'm trying to customize dslv with right handle. I'm using BaseAdapter whose code is given below:

my listview adapter code: package com.tekege.warptime.widget;

import java.util.ArrayList;

import android.content.Context; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.LinearLayout;

public class DragSwipListViewAdapter extends BaseAdapter implements RemoveListener, DropListener {

private LinearLayout linear_layout_timezone;
private ArrayList<LinearLayout> mContent;
Context context;

public DragSwipListViewAdapter(Context context, ArrayList<LinearLayout> content) {
    this.context = context;
    mContent = content;
}

@Override
public int getCount() {
    return mContent.size();
}

@Override
public LinearLayout getItem(int position) {
    return mContent.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

// View v = super.getView(position, convertView, parent); try{ linear_layout_timezone = (LinearLayout) mContent.get(position); } catch(Exception e){ e.printStackTrace(); } return linear_layout_timezone; }

@Override
public void onDrop(int from, int to) {
    try{
        LinearLayout temp = mContent.get(from);
        mContent.remove(from);
        mContent.add(to, temp);
    }
    catch(Exception e){
        e.printStackTrace();
    }
}

@Override
public void onRemove(int which) {
    try{
        if (which < 0 || which > mContent.size())
            return;
        mContent.remove(which);
    }
    catch(Exception e){
        e.printStackTrace();
    }
}

}

I'm adding items with this xml:

I'm adding array list of linear layout using custom base adapter. But when I drag item it works fine but when I drop item it throw following error:
